Do road bikes buy disc brakes or ring brake systems? To be professional
The well-known car shop owner Shu Mi
Jokingly: “Children make choices, adults buy them all!” ”
Objectively looking at this matter, in this year’s Tour de France, the yellowshirt riders
, use disc brakes at Pinglu Station, and ring brakes at mountaineering stations, so they have their own strengths, to buy disc brakes or ring brakes, it depends on your own needs.

It’s all riding lap brakes.
Shu Mi also mentioned that although most of the teams in the Tour de France use disc brakes, the reason is that the car manufacturers now mainly push the disc brakes, and even some car manufacturers only issue disc brakes. He also recalled more than a decade ago,
In fact, I also experienced a conversion process between circle brakes and disc brakes, at that time
The clamp brake was quickly eliminated because
On muddy roads, weather resistance is also more important.
Years or so, Shu Mi once assembled a disc brake road car, but the axle width was still at that time
‘s quick release, now it is
The stability is also better. So why did the controversy over the use of disc brakes on road cars last so long?
Of course, there are still some problems with disc brakes, such as disc brakes to pay special attention to maintenance, if discs or brakes to make the disc excessive wear, it may cause danger; The hydraulic disc brake should be exhausted when filling oil, and if it is not done well, the hydraulic conduction will be affected, and the feel will be bad. Of course, the cost of its consumables is relatively high compared to the ring brake.
And not everyone likes disc brakes, like the four-time Tour de France yellow shirt winner
As far as he has an opinion on switching to disc brakes, he does not trust disc brakes 100% for long-term, high-intensity and long-distance use! Although the disc brake performance is relatively good, if you are like a professional player, the disc may overheat and deform in a long-term high-speed downhill; The disc grinds to the caliper to make the piece, and the noise produced is also unbearable; There are also disc brakes that produce a twist of the fork when actuated.
Shu fan believes that disc brake road bikes still have room for improvement, there are still some problems, standing on the bicycle is a tool for mobile efficiency conversion, the simpler the better,
The clip is in line with this “simple is good” principle, so there will still be room for its existence. So he believes that in the consumer market, the ring brake should still exist, and in terms of competition, it seems that the disc brake is stronger at present.

Shu Mi also directly compared two cars of the same model, but each equipped with disc brakes and disc brakes, from the perspective of circle brakes, wiring is very important, affecting whether the brakes are smooth. He mentioned that some women because of their small hands, will feel that the brake of the ring brake is relatively difficult to press, the disc brake is relatively good brake, but its performance in the circle brake does not need to be pressed too hard, and there is also a version of the small hand change handle.
In addition, a difference between the ring brake and the disc brake is that the ring brake is a two-sided clamp to brake, and the disc brake is a one-sided clamp, so when braking, the force of the disc brake wheel set is only unilateral, less even, it will twist, like motorcycles, single disc discs will have this problem; But if you want to use bilateral discs after motorcycles, it will be heavier.
In addition, the circle brake is in
The space in the clamp is relatively large, and the brake pad is not easy to grind to the rim, but the disc brake makes the disc very close to the disc, coupled with a long downhill, the temperature is very high, and the disc may be deformed, so the chance of grinding is high. If the disc can grind the clamper, it may not be adjusted well for half a day, and professional technicians sometimes have to adjust for a long time.
In terms of rigidity, disc brakes use a through-shaft, and its rigidity will be relatively high
The quick release of the clamp will have a lower rigidity, and the difference will be felt when cornering and braking, and the disc brake is better in the torsional rigidity of the fork. But the disc disc is on one side, so it will twist when braking, so the disc brake is not perfect.
Finally, in terms of weight, there will be a difference, the ring brake is still more advantageous in weight, he estimates that the same style, the same level of car, with disc brakes will be about heavier than the ring brake
； In particular, disc brakes are heavy on the wheels, and they have the problem of moment of inertia, so in mountaineering races, riders will of course choose lap brakes.
Finally, returning to the perspective of general riders, Shu fans believe that the weather resistance of disc brakes is indeed better, but riders should think about whether they will ride on rainy days; The second is that the braking performance is better, but Shu fan believes that it is more important for riders to learn how to master the brakes, not to say that the situation will brake sharply, the disc brake can grasp the wheel, but the wheel may not be able to grasp the ground, in fact, it is very dangerous. Moreover, although the disc brake will not have the problem of burning the frame, but the disc itself will also burn out, and he believes that whether it will burn the frame is related to the use of the rider itself, and now the drainage brake side design of the ring brake wheel set has made great progress, and the ring brake does not necessarily burn the frame.
Finally, he concluded that at present, the circle brake and the disc brake are each good at winning, but the brakes are constantly improving, and the disc brakes are still worth looking forward to. And riders who like to circle brakes can also take this opportunity to pick up some second-hand wheels and use them back.
